From what I have noticed personally, If you belong to the forum and you see another 370 you always wave.
Im always gonna wave at a 350,370, or GTR, but if they're not part of the forum they usually give me the pissing contest look like "my car is better!"
Also plenty of weird "why is this guy waving at me?" looks from the bone stock owners
***Side note: In Orlando, the first week I got my 370 I was driving back from getting my windows tinted and saw a guy down a side road that must have lived by me (waterford lakes area). He was right in front me and I wanted to see if he was a forum member and I couldn't roll down my window to say anything. I was sitting in my car like
